A sample X.509 certificate, which is a copy of the BMC and the EMA Platform Mode certificate, is shipped along with the
shipment. The size of this certificate is 2,000 bytes.

Security Enhancement to Allow Only One Concurrent EMA Session
| Info |
|---|
This security enhancement is available beginning with SBC Core version 06.02.00R000. |
This enhancement enables the EMA application (including EMA in platform mode) to disable concurrent user sessions. Once a new session is established, any existing session is terminated immediately. When an EMA user attempts to log in, the system checks for any open sessions with the same username. If any existing user session is identified, that user is immediately logged out from the application and allows the new user to log in to the system.
| Info |
|---|
|
This feature is applicable to all EMA users (local users, radius users, PKI certificate-based users, and CAC users). |
